Press accounts speculate that the staunch anti-gun-control group deleted its page amid a growing and impassioned debate over whether gun laws need tightening. A woman answering phones at the NRA’s public affairs office declined to immediately comment on the Facebook page Monday. When asked whether the Facebook move was indeed voluntary, she responded, “I do not know, sir.” The association touted its 1.7 millionth Facebook “like” in a tweet midday Thursday, prompting an fusillade of angry replies the following day, after the school shooting. An early-morning Friday tweet about NRA giveaways prompted a similar backlash and the group has not tweeted since.
